JTable & Edit Button Click - Plz Help
Dear All
I am using JTable. I need suggestion regarding following. Please help me out.
I need suggesgtion that at background what should i use to know that a particular row is added,edit,delete or a certain operation is done.
All the following operation are done after clicking Edit Button.
1. I have add button to add row into jTable.
2. I have edit button to edit a particular row. And there is another column with combobox that shows that if "YES" is selected then only "YES" option value are updated. Is this correct.....?
3. I have delete button to remove a particular row. How do i know if 3 rows are deleted randomly out of 10 rows. (Shoud i use vector or something else)
4. What if Row # 3 is deleted and another Row is added at last. How do i know that which row is added as total rows are 10 in both cases (delete/add row).
5. How do i know that particular row is edited. Let column 1 has code = 1001 and that column value is now change to 1002. (I think i can get this from YES option as i defined in Q#2.) Is this correct.
Please help me what technique should i use to handle my all required events.
Answer me if you can help me out regarding any of above scneario.
Thanks in advance.

Hello,
The following might help you on how to resolve your problem
construct a Jtable having DefaultTableModel with data express using vector ,vector
Add a global variables to listen to the row or column
public int G_row,G_Col
myModel = new MyTableModel(columnNames, 5);
myModel.setDataVector(my_data2, columnNames);
table = new JTable(myModel);
table.addMouseListener(new MouseClickHandler());
private class MouseClickHandler extends MouseAdapter {
public void mouseClicked(MouseEvent event) {
no_mouseclick = event.getClickCount();
}
overidding your DefaulttableModel like
public boolean isCellEditable(int row, int col) {
boolean isedit false;
G_row = row;
G_Col=col;
// Add something to listen for the action request,
//may be double mouse click through mouselistener would enable a particular cell to true
private class MouseClickHandler extends MouseAdapter {
public void mouseClicked(MouseEvent event) {
no_mouseclick = event.getClickCount();
if no_mouseclick>=2
isedit= true;
}
In your Jtable add two button b1 for edit , b2 for delete
JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(1, 3));
JButton b1 = new JButton("Edit row");
b1.setMnemonic(KeyEvent.VK_A);
b1.setToolTipText("Edit row");
JButton b2 = new JButton("Delete row");
b2.setMnemonic(KeyEvent.VK_D);
p1.add(b1);
p1.add(b2);
b1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// peform your edting routine here
myModel.fireTableRowsUpdated(0, myModel.getRowCount());
//System.out.println(myModel.getRowCount());
}
});
b2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (table.getSelectedRow() > -1) {
int i = JOptionPane.showConfirmDialog(null,
"Confirm Remove Selected Row ?",
"CONFIRM DELETE",
JOptionPane.YES_NO_OPTION,
JOptionPane.INFORMATION_MESSAGE);
if (i == JOptionPane.YES_OPTION) {
int tblrow=table.getRowCount();
myModel.removeRow(table.getSelectedRow());
myModel.fireTableRowsDeleted(0,
tblrow);
// myModel.fireTableDataChanged();
}
} else {
JOptionPane.showMessageDialog(null,
"please select row to remove");
}
// myModel.fireTableDataChanged();
}
If your need more example, pls post again
